During an upper endoscopy procedure, the gastroenterologists almosttry to make adiagnosis of gastric lesions using observational features via an endoscope.

In a prospective study on outpatients fromMay 2015toMarch 2017, patients who were referred to endoscopy ward in a referral center were enrolled in study. The exclusion criteria were: contraindication for biopsy, definite diagnosis, needing for therapeutic procedure and follow-up endoscopy. The upper endoscopy was performed by two gastroenterologists. The stomach mapping was performed in various parts of the body includingfundus, body (lesser and greater curvatures) and antrum andtwo biopsy samples were taken from each area. Samples were then stored in separate bottles. Soon after,the specimens were transferredto the central pathology ward of the hospital. Associationbetween the endoscopy and pathology findings were assessed.

The mean age was 51±6. 207 patients (59.1%) were male. Generally the majority of the lesions were located in the antrum .The sensitivity of endoscopy for fundus, body and antrum was 33.3%,49.4% and 70.6%, respectively.Additionally, specificity of endoscopy for fundus, body and antrum was 97.5%, 93.5% and 90.6%, respectively. The endoscopy findingsfor atrophy and metaplasia in antrum had relatively low association with pathology findings.

These findings indicated that additional detailedendoscopy reports and histopathological studiesare required to be performed in order to achieve better outcome for accurate diagnosis.
